The UV absorbers according to the present invention can be used either in the dissolved state (soluble organic filters, solubilised organic filters) or in the micronised state (nanoscalar organic filters, particulate organic filters, UV-absorber pigments).

Any known process suitable for the preparation of microparticles can be used for the preparation of the micronised UV absorbers, for example: wet-milling (low-viscosity micronisation process for pumpable dispersions), with a hard grinding medium, for example zirconium silicate balls in a ball mill, and a protective surfactant or a protective polymer in water or in a suitable organic solvent; wet-kneading (high-viscosity micronisation process for non-pumpable pastes) using a continuous or discontinuous (batch) kneader. For a wet-kneading process, a solvent (water or cosmetically acceptable oils), a grinding aid (surfactant, emulsifier) and a polymeric grinding aid may be used.

Both processes may be used preferably.

spray-drying from a suitable solvent, for example aqueous suspensions or suspensions containing organic solvents, or true solutions in water, ethanol, dichloroethane, toluene or N-methylpyrrolidone etc..

by expansion according to the RESS process (Rapid Expansion of Supercritical Solutions) of supercritical fluids CO2) in which the UV filter or filters is/are dissolved, or the expansion of liquid carbon dioxide together with a solution of one or more UV filters in a suitable organic solvent; by reprecipitation from suitable solvents, including supercritical fluids (GASR process Gas Anti-Solvent Recrystallisation PCA process Precipitation with Compressed Antisolvents).

WO 2004/006878 PCT/EP2003/006955 -24- As milling apparatus for the preparation of the micronised organic UV absorbers there may be used, for example, a jet mill, ball mill, vibratory mill or hammer mill, preferably a highspeed mixing mill. Even more preferable mills are modern ball mills; manufacturers of these types of mill are, for example, Netzsch (LMZ mill), Drais (DCP-Viscoflow or Cosmo), Bihler AG (centrifugal mills) or Bachhofer. The grinding is preferably carried out with a grinding aid.

Examples of kneading apparatus for the preparation of the micronised organic UV absorbers are typical sigma-blade batch kneaders but also serial batch kneaders (IKA-Werke) or continuous kneaders (Continua from Werner und Pfleiderer).

Useful low molecular weight grinding aids for all the above micronisation processes are surfactants and emulsifiers as disclosed below in the sections entitled "Emulsifiers", "Surfactants" and "Fatty alcohols".

Useful polymeric grinding aids for water dispersion are cosmetically acceptable water-soluble polymers with Mn 500 g/mol, for example: acrylates (Salcare types), modified or nonmodified polysaccharides, polyglucosides or xanthan gum. Furthermore an alkylated vinylpyrrolidone polymer, a vinylpyrrolidone/vinyl acetate copolymer, an acyl glutamate, an alkyl polyglucoside, Ceteareth-25 or a phospholipid may be used. Oil dispersions may comprise cosmetically acceptable waxy polymers or natural waxes as polymeric grinding aid to adjust the viscosity during and after processing. Examples of other useful polymeric grinding aids are disclosed below in the section entitled "Polymers".

Useful solvents are water, brine, (poly-)ethylene glycol, glycerol or cosmetically acceptable oils. Other useful solvents are disclosed below in the sections entitled "Esters of fatty acids", "Natural and synthetic triglycerides, including glyceryl esters and derivatives", "Pearlescent waxes", "Hydrocarbon oils" and "Silicones or siloxanes".

The micronised UV absorbers so obtained usually have an average particle size from 0.02 to 2 micrometres, preferably from 0.03 to 1.5 micrometres and more especially from 0.05 to micrometres.

WO 2004/006878 PCT/EP2003/006955 The UV absorbers according to the present invention can also be used dry in powder form.

For that purpose, the UV absorbers are subjected to known grinding methods, such as vacuum atomisation, countercurrent spray-drying etc.. Such powders have a particle size of from 0.1 micrometres to 2 micrometres. To avoid the occurrence of agglomeration, the UV absorbers can be coated with a surface-active compound prior to the pulverisation process, for example with an anionic, non-ionic or amphoteric surfactant, e.g. a phospholipid or a known polymer, such as PVP, an acrylate etc..

The UV absorbers according to the present invention can also be used in specific carriers for cosmetics, for example in solid lipid nanoparticles (SLN) or in inert sol-gel microcapsules wherein the UV absorbers are encapsulated.

The cosmetic formulations or pharmaceutical compositions according to the present invention can also comprise one or more than one further UV filter as described in Tables 1-3.

The cosmetic or pharmaceutical preparations can be prepared by physically mixing the UV absorber(s) with the adjuvant using customary methods, for example by simply stirring together the individual components, especially by making use of the dissolution properties of already known cosmetic UV absorbers, for example octyl methoxycinnamate, salicylic acid isooctyl ester etc.. The UV absorber can be used, for example, without further treatment, or in the micronised state, or in the form of a powder.

Cosmetic or pharmaceutical preparations contain from 0.05 to 40 by weight, based on the total weight of the composition, of one UV absorber or a mixture of UV absorbers.

Preference is given to the use of mixing ratios of the UV absorber of formula according to the present invention and optional further light-protective agents (as described in Tables 1-3) of from 1:99 to 99:1, especially from 1:95 to 95:1 and preferably from 10:90 to 90:10, based on weight. Of special interest are mixing ratios of from 20:80 to 80:20, especially from 40:60 to 60:40 and preferably approximately 50:50. Such mixtures can be used, inter alia, to improve solubility or increase UV absorption.

WO 2004/006878 WO 204/06878PCTIEP2003/006955 26 The UV absorbers of formula according to the present invention or combinations of UV filters are useful for protecting skin, hair and/or natural or artificial hair colour.

Further synthetic and natural antioxidants are listed e.g. in patent WO 0025731: WO 2004/006878 PCT/EP2003/006955 -41 structures 1-3 (page structure 4 (page structures 5-6 (page 7) and compounds 7-33 (page 8-14).

The amount of antioxidants present is usually from 0.001 to 30 by weight, preferably from 0.01 to 3 by weight, based on the weight of the UV absorber of formula Hvdrotropic agents To improve the flow behaviour it is also possible to employ hydrotropic agents, for example ethoxylated or non ethoxylated mono-alcohols, diols or polyols with a low number of carbon atoms or their ethers ethanol, isopropanol, 1,2-dipropanediol, propylene glycol, glycerol, ethylene glycol, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monobutyl ether, diethylene glycol monomethyl ether; diethylene glycol monoethyl ether, diethylene glycol monobutyl ether and similar products). The polyols that come into consideration for that purpose have preferably from 2 to 15 carbon atoms and at least two hydroxy groups.

The polyols may also contain further functional groups, especially amino groups, and/or may be modified with nitrogen. Typical examples are as follows: glycerol, alkylene glycols, for example ethylene glycol, diethylene glycol, propylene glycol, butylene glycol, hexylene glycol and also polyethylene glycols having an average molecular weight of from 100 to 1000 Dalton; technical-grade oligoglycerol mixtures having an intrinsic degree of condensation of from 1.5 to 10, for example technical-grade diglycerol mixtures having a diglycerol content of from 40 to 50 by weight; methylol compounds, such as, especially, trimethylolethane, trimethylolpropane, trimethylolbutane, pentaerythritol and dipentaerythritol; lower alkyl-glucosides, especially those having from 1 to 8 carbon atoms in the alkyl radical, for example methyl and butyl glucoside; sugar alcohols having from 5 to 12 carbon atoms, for example sorbitol or mannitol; sugars having from 5 to 12 carbon atoms, for example glucose or saccharose; amino sugars, for example glucamine; dialcohol amines, such as diethanolamine or 2-amino-1,3-propanediol.

Preservatives and bacteria-inhibiting agents Suitable preservatives include, for example, methyl, ethyl, propyl and butyl parabens, benzalkonium chloride, 2-bromo-2-nitro-propane-1,3-diol, dehydroacetic acid, diazolidinyl urea, 2-dichloro-benzyl alcohol, DMDM hydantoin, formaldehyde solution, methyldibromoglutanitrile, phenoxyethanol, sodium hydroxymethylglycinate, imidazolidinyl urea, triclosan WO 2004/006878 PCT/EP2003/006955 -42and further substance classes listed in the following reference: K.F.DePolo A short textbook of cosmetology, Chapter 7, Table 7-2, 7-3, 7-4 and 7-5, p210-219.

Bacteria-inhibiting agents Typical examples of bacteria-inhibiting agents are preservatives that have a specific action against gram-positive bacteria, such as 2,4,4'-trichloro-2'-hydroxydiphenyl ether, chlorhexidine (1,6-di(4-chlorophenyl-biguanido)hexane) or TCC (3,4,4'-trichlorocarbanilide).

A large number of aromatic substances and ethereal oils also have antimicrobial properties.

Typical examples are the active ingredients eugenol, menthol and thymol in clove oil, mint oil and thyme oil. A natural deodorising agent of interest is the terpene alcohol farnesol (3,7,11trimethyl-2,6,10-dodecatrien-1-ol), which is present in lime blossom oil. Glycerol monolaurate has also proved to be a bacteriostatic agent. The amount of the additional bacteria-inhibiting agents present is usually from 0.1 to 2 by weight, based on the solids content of the preparations.

Perfume oils There may be mentioned as perfume oils mixtures of natural and/or synthetic aromatic substances. Natural aromatic substances are, for example, extracts from blossom (lilies, lavender, roses, jasmine, neroli, ylang-ylang), from stems and leaves (geranium, patchouli, petitgrain), from fruit (aniseed, coriander, carraway, juniper), from fruit peel (bergamot, lemons, oranges), from roots (mace, angelica, celery, cardamom, costus, iris, calmus), from wood (pinewood, sandalwood, guaiacum wood, cedarwood, rosewood), from herbs and grasses (tarragon, lemon grass, sage, thyme), from needles and twigs (spruce, pine, Scots pine, mountain pine), from resins and balsams (galbanum, elemi, benzoin, myrrh, olibanum, opoponax). Animal raw materials also come into consideration, for example civet and castoreum. Typical synthetic aromatic substances are, for example, products of the ester, ether, aldehyde, ketone, alcohol or hydrocarbon type. Aromatic substance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethylmethylphenyl glycinate, allylcyclohexyl propionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether; the aldehydes include, for example, the linear alkanals having from 8 to 18 hydrocarbon atoms, citral, citronellal, citronellyl oxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal; the ketones include, for example, the ionones, isomethylionone and methyl WO 2004/006878 PCT/EP2003/006955 -43cedryl ketone; the alcohols include, for example, anethol, citronellol, eugenol, isoeugenol, geraniol, linalool, phenyl ethyl alcohol and terpinol; and the hydrocarbons include mainly the terpenes and balsams. It is preferable, however, to use mixtures of various aromatic substances that together produce an attractive scent. Ethereal oils of relatively low volatility, which are chiefly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, clove oil, melissa oil, oil of cinnamon leaves, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil, labdanum oil and lavandin oil. Preference is given to the use of bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenyl ethyl alcohol, hexyl cinnamaldehyde, geraniol, benzyl acetone, cyclamen aldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, lemon oil, tangerine oil, orange oil, allyl amyl glycolate, cyclovertal, lavandin oil, muscatel sage oil, damascone, bourbon geranium oil, cyclohexyl salicylate, vertofix coeur, iso-E-Super, Fixolide NP, evernyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romillat, irotyl and floramat alone or in admixture with one another.

Colorants There may be used as colorants the substances that are suitable and permitted for cosmetic purposes, as compiled, for example, in the publication "Kosmetische Farbemittel" of the Farbstoffkommission der Deutschen Forschungsgemeinschaft, Verlag Chemie, Weinheim, 1984, pages 81 to 106. The colorants are usually used in concentrations of from 0.001 to 0.1 by weight, based on the total mixture.

Other adjuvants It is furthermore possible for the cosmetic preparations to comprise, as adjuvants, antifoams, such as silicones, structurants, such as maleic acid, solubilisers, such as ethylene glycol, propylene glycol, glycerol or diethylene glycol, opacifiers, such as latex, styrene/PVP or styrene/acrylamide copolymers, complexing agents, such as EDTA, NTA, alaninediacetic acid or phosphonic acids, propellants, such as propane/butane mixtures, N 2 0, dimethyl ether, CO 2

N

2 or air, so-called coupler and developer components as oxidation dye precursors, reducing agents, such as thioglycolic acid and derivatives thereof, thiolactic acid, cysteamine, thiomalic acid or mercaptoethanesulfonic acid, or oxidising agents, such as hydrogen peroxide, potassium bromate or sodium bromate.

WO 2004/006878 PCT/EP2003/006955 -44- Suitable insect repellents are, for example, N,N-diethyl-m-toluamide, 1,2-pentanediol or insect repellent 3535; suitable self-tanning agents are, for example, dihydroxyacetone and/or erythrulose or dihydroxy acetone and/or dihydroxy acetone precursors as described in WO 01/85124 and/or erythrulose.

Polymeric beads or hollow spheres as SPF enhancers The combination of the UV-absorbers and UV-absorber combinations, listed above, with SPF enhancers, such as non-active ingredients like styrene/acrylate copolymers, silica beads, spheroidal magnesium silicate, crosslinked polymethylmethacrylates (PMMA; Micopearl M305 Seppic), can maximize the UV protection of the sun products. Hollow-sphere additives (Sunspheres® ISP, Silica Shells Kobo.) deflect radiation and the effective path length of the photon is therefore increased (EP 0 893 119). Some beads, as mentioned previously, provide a soft feel during spreading. Moreover, the optical activity of such beads, e.g.

Micropearl M305, can modulate skin-shine by eliminating reflection phenomena and may indirectly scatter the UV light.
